Katy Perry took to Twitter and urged citizens to donate for the child.

She wrote, ” My ? was touched by Carter’s story. If you’re able pls help w/ his chance to defeat Childhood Alzheimer’s. He’s SO close to funding his clinical trial & I would love to see my KatyCats kick it over the goal & make that difference! I’m donating now too! ?? https://www.gofundme.com/savingcarter”

The disease is named after Sylvester Sanfilippo, the pediatrician who first described the disease which many called it as “children’s Alzheimer’s.”

It’s a neurodegenerative disease which affects one in every 70,000 children.
